Overall, I can't help but notice that again, -aiden names are decreasing almost across the board. They partially seem to be getting replaced by -ason (and -aceon?).
As for the girls' Top 10: Sophia & Isabella are slowly losing ground--Emma, Elizabeth, and Ava saw almost no change, though, and Emily, Madison, & Abigail also lost %. Will Olivia & Mia be top next year? Or will something come up from further down the rankings--Charlotte? Avery? Harper?
